Hello,
I have trouble with using data.frame data.
1. I loaded data using the following:
ff <- read.table("E:/R/VM/matrix.txt", header=T)
The data I used is attached.
I want to use at least 2 conditions for selecting of data. But I failed.
It works. ->
fff <- ff[ff$HG == "GUEST",]
ffff <- fff[fff$WR == "READ",]
But it doesn't work -> ff[ff$HG == "GUEST",ff$WR=="READ"]
How can I use 2 or more conditions together in one sentence ?
2. I want to plot Throuput data using BlockSize as x-axis like the following:
plot(ffff$BlockSize, ffff$Throughput, type="o")
But, Gap between 2 axis values are not consistent in the graph.
So I tried to use log() like the following:
plot( log(ffff$BlockSize), ffff$Throughput, type="o")
The problem seems to be fixed.
But x-axis sting is shown not as (1,2,4,8,16,32,64,128) but as (0,1,2,3,4,5),
which is not my intention.
How can I fix this problem ?
Thanks in advance,
SK Park
